SPECIFICATION forming part of Letters Patent No. 643,176, dated February 13, 1900.

TO (til whom, it fitay concrn:

Be it known that I, OARL HEINRICH J ULIUS NIESE, a citizen of free city of Hamburg, residing at Hamburgfln the Empire of Germany, have invented certain new and useful Improvements in lVater-lVheels, (for which I have applied for patents in England, dated February 2, 1898, No. 2,707; in Austria, dated February 4, 1898; in Hungary, dated February 5, 1898, No. 1,753; in Germany, dated January 29, 1898; in France, dated February 2, 1898, No. 262,&28; in Belgium, dated February, 1, 1898, No. 104049; in Sweden, dated January-'31, 1898, No. 165; in Norway, dated February 4, 1898, No. 9,437, and in Switzerland, dated February 2, 1898, No. 17,622,) of which the following is a specification.

The present invention relates to a waterwheel which is designed to utilize the motive force of flowing water without necessitating any artificial damming up of the water or requiring a vertical fall of water for its operation. The water-Wheelmay therefore be immersecl direct in any stream which fiows sufiiciently fast to possess an appreciable amount of motive force.

In the accompanying drawings, in which the water-wheel is illustrated, Figure 1 is a top plan view of the wheel with the parts transmitting the power from the wheel-shaft omitted. Fig. 2 shows a vertical section of the wheel perpendicular to the direction of the stream.

Upon the vertical shaft a, which turns at. its lower end in a step-bearing n and at its upper end in a bearing in a bracket m, fixed to a wall on the bank, are mounted a series of arms c, forming a wheel, which is connected to the shaft by a t'eather in such manner that the shaft must rotate with the wheel. The keyway being of consider-able length, the wheel is free to rise and fall on the shaft as the water-level sinks or rises.

zontal arm f, :t'orged with the bolt, permits of is so calculated thatthe lifting power of the i float b allows of the complete immersion, or nearly so, of the blades when in a vertical position.

Supposing now the fiow of the stream to be in the direction of the arrows, Fig.1, one-half of the blades pendent from the arms f will be vertical, being prevented by the stops s from tnrning further by the stream. Through the resistance which the blades offer to the stream the series of arms are set in rotation. Assuming that at starting the position of the blades was at right angles to the direction of the stream at u, they will as they move onward remain parallel to each other, as the Currents of the stream eXert an equal pressure on both edges of the pivot-pins e, and the balance is therefore not disturbed. As soon, however, as the movement of the blades changes from one at right angles to the direction of the stream the lateral pressure begins to act. The blades are then thrown out of equilibrium and, following the waterpressure, turn about the bolt e, as at e. They thus present their other sides to the current, and as the stops r in this position do not prevent their turning on the hinge-arm f the blades lie flat on the water and offer no appreciable resistance thereto. When the position of the blades is again vertical to the direction of the stream, as at w, the reverse action takes place, the blades turn to their vertical position, and, with their original sides to the stream, they again ofier resistance to the water. Ohains t' are provided for preventing the blades from turning too far at the points o and w. The shaft a is thus on the rotation of the wheel c carried around with it and transmitsits power through bevel-wheels y to a shaft z.

What I claim, and desire to secure by Letters Patent of the United States, is

A wheel for utilizing the power of flowing 2 &13,176
